XFLR5 Help

[KDorka]

Hi,

I've got some co-ordinates that i want to put into XLFR5 however it doesn't seem to recognise the points apart from the first one. I realise that the shape isn't really an aerofoil and was wondering if this had anything to do with it? I am basically importing co-ordinates from a CAD model that was set up.

Many thanks for your help in advance!

Also the points aren't between 0 and 1 in the x direction and not between -1 to 1 in the y direction. Does this also have any influence?

This is a version with X between 0 and 1, and Y between -1 and 1 however i am still encountering the same problem. I have attached the new file to this post. Any help would be much appreciated!

Try removing the tabs and replacing them with spaces

The tool and target do not form a complete intersection.

OK, shift it right so no negative x values, and then normalize X and Y, and replace tabs with spaces, and it works

The tool and target do not form a complete intersection.

I followed what you said however i still can't get the co-ordinates to import? Please can you look at the attached .dat file

OK I took a closer look... your line endings are encoded as a mix between \n and \r. It appears that XFLR5 only recognizes either \n or \n\r. To see them using notepad++ do View->show symbol->show end of line. The only reason my earlier changes worked is because it was re-saved with default windows line endings - so who knows if any of that stuff is necessary. For more info on line endings see

You need to replace all your line endings with either \n or \n\r so in notepad++ do a find-replace, check the box "search mode extended", and replace \r with \r\n. Or maybe there is a setting in your software to save using windows line endings.
